Alina was elated when Hendrick couldn't attend the tea party. She wouldn't have to pretend all sweet to him again since she had to act like she was in love with the latter.
After all, their marriage was delayed due to the war. She had to keep up the act. And much to her dismay, not only was Princess Valerie supposed to become his wife but also Princess Cassandra.
Alina almost gave up on the marriage with him due to that. With two rival princesses, Alina, who was a mere lady now, would be nothing.
She thought that Hendrick would break the engagement with her but he was a man of his word. He was still keen on keeping his word that she would be his duchess.
And as if as a token that his promise to her stands true no matter what, he consummated with her in the Valyenor Mansion before they attended the victory celebration in Valyenor.
